摘要:
A family of water-based gas-generating liquid compositions is described. A composition of the present invention includes: a first compound which may be hydrazinium mononitrate or methylhydrazinium mononitrate; ammonium nitrate; and water. Compositions of the present invention may be mixed with fuels to make monopropellants or used in bipropellant or hybrid systems. Alternative uses of the present invention include breathable gas generation.
摘要:
Inorganic nitrate oxidizers are combined in novel eutectic compositions which place the oxidizers in liquid form at ambient temperatures. These liquid combinations are then used in the preparation of a wide variety of energetic formulations, notably solution and emulsion propellants.
摘要:
Liquid monomethylhydrazine is converted to a thiotropic gel by dispersing erein a cellulose or hydroxyalkyl-substituted gelling agent. The gel thus obtained can be handled and stored on board a rocket motor without the hazards associated with liquid monomethylhydrazine.

The present invention comprises a solid double-base propellant composition having on a weight basis from about 2 to about 23 percent of a light metal fuel, from about 14 to about 35 percent of a particulate solid oxidizer, from about 12 to about 35 percent triaminoguanidinium hydrazinium diazide and from about 30 to about 50 percent of a plasticized nitrocellulose binder.
摘要:
The present invention relates to stable, high energy compositions for utilization as monopropellants in reaction engines or as explosives, depending upon proportionation of ingredients. More particularly, the present invention relates to preferably thixotropic compositions comprising a particulate metal fuel and hydrazinium nitrate as an oxidizer, coupled with one or more working fluid and desensitizer ingredients, providing high performance and high bulk density with very good physical and chemical stability. Specifically, high energy reaction systems according to the invention utilize beryllium, aluminum, and mixtures thereof as the metal fuel contributing constituent, utilize hydrazinium nitrate as the oxidizer contributing constituent, and utilize as the working fluid and desensitizer a hydrazine containing material with one or more ingredients selected from the group consisting of hydrazine, monomethylhydrazine, unsymmetrical dimethylhydrazine, and mixtures thereof with water.
摘要:
Liquid propellant fuels such as liquid hydrazines, amine fuels, and blends thereof with hydrocarbons used as storable fuels for supersonic combustion in ramjets. The storable liquid fuel is decomposed in flight into a hot hydrogen-containing gas which is then injected into a supersonic air stream and subsequently oxidized in a supersonic combustion mode.
